kess v2 problem writing gran cherokee 3.0 crd

[ivanrojo]

hello all, i have a reworked kess v2 fw 4.036 and sw 2.08, i can read and made id to the car ( gran cherokee 3.0 crd) but when i try to write the modified file a error appears saying: error checksum buffer, checksum is corrected with winols I have checked it several time but nothing changes.

does someone know if problem is on the tool or maybe is not a supported model?

thanks!
